ProMax 16mm Metal Piezo Touch Switch Waterproof IP68 Momentary Red Green
The ProMax 16mm Metal Piezo Touch Switch is a premium momentary contact switch featuring capacitive piezo technology with dual color LED indicators in red and green. This industrial-grade switch is engineered for applications requiring reliable tactile feedback in harsh environments, delivering IP68 waterproof protection against dust, moisture, and submersion up to 1 meter for 30 minutes. Automation engineers, control panel designers, and industrial equipment manufacturers rely on this switch for mission-critical applications where durability and responsiveness are non-negotiable.
Product Overview
The ProMax piezo touch switch operates on capacitive sensing technology, eliminating mechanical wear associated with traditional push-button switches. When activated, the piezo element generates a haptic feedback pulse that provides tactile confirmation to the operator, while simultaneously triggering the momentary electrical contact. The dual-color LED system allows simultaneous status indication: the red LED indicates standby or alert mode, while the green LED confirms active operation or system readiness. This visual feedback mechanism is critical in control rooms and industrial dashboards where operators need instantaneous confirmation of switch state without relying solely on auditory cues.
The 16mm metal housing is constructed from marine-grade stainless steel with an anodized aluminum bezel, providing exceptional corrosion resistance in coastal, chemical, and food processing environments. The IP68 rating ensures complete protection against ingress of dust particles and water immersion, making it suitable for washdown applications, outdoor installations, and subsurface equipment housings. The momentary contact configuration means the switch returns to its default state immediately upon release, preventing accidental sustained activation and making it ideal for emergency stop systems, pump controls, and signal transmission in automated manufacturing lines.

How to Use
Installation of the ProMax 16mm piezo touch switch requires a standard 16mm diameter panel cutout with a depth clearance of 35mm behind the panel surface. Secure the switch using the provided stainless steel locking ring, ensuring a watertight seal by applying a thin bead of silicone sealant around the panel interface. Connect the switch terminals to your control circuit: the common terminal connects to your DC power supply (12V or 24V), the momentary contact output connects to your load or control relay, and the LED ground connections to your indicator circuit. For dual LED operation, connect the red LED positive terminal to a 220-ohm current-limiting resistor before connecting to your 12V supply, and similarly for the green LED to enable independent color control based on system state.
Before commissioning, test the switch response time using an oscilloscope or digital multimeter set to continuity mode, confirming activation occurs within 50 milliseconds of finger contact. Verify the haptic feedback vibration is perceptible by making light contact with the switch surface. For applications requiring submersion protection, ensure the panel cutout is sealed with the provided silicone gasket and locking ring is tightened to specification (8-10 Newton-meters) to maintain IP68 rating. In harsh chemical environments, inspect the stainless steel housing quarterly for any surface corrosion and clean with a soft cloth dampened with distilled water. Never use abrasive cleaners or steel wool on the anodized bezel as this will compromise the corrosion-resistant coating.
Frequently Asked Questions
What is the difference between IP67 and IP68 ratings for this switch?
IP67 rating allows temporary immersion in water up to 1 meter for 30 minutes, while IP68 rating on the ProMax switch exceeds this standard by allowing continuous submersion at depths greater than 1 meter. The IP68 rating means this switch can operate reliably in permanently wet environments like underwater equipment housings, submerged pump control panels, and flood-prone industrial facilities. The sealed piezo design with stainless steel housing ensures no water ingress even under sustained pressure conditions.
Can I use this switch with AC power supplies instead of DC 12V or 24V?
The ProMax piezo touch switch is engineered exclusively for DC power operation. The piezo sensing element and LED indicators require DC voltage to function properly. Using AC power will damage the internal capacitive sensing circuit and LED components. If your application requires AC operation, you must use an external AC to DC converter rated for at least 500mA at your required voltage (12V or 24V), then connect the DC output to the switch terminals. This approach maintains the switch integrity while allowing integration with AC control systems.
What is the maximum current the switch contacts can handle without degradation?
The ProMax switch contacts are rated for a maximum continuous current of 500mA at DC 24V. Exceeding this rating will cause rapid contact erosion and switch failure. For applications requiring higher current switching (such as directly controlling high-power motors or heating elements), use the switch output to trigger a relay or solid-state switch rated for your load current. This approach protects the delicate piezo contacts while allowing the switch to control high-power circuits reliably.
How do I maintain the IP68 waterproof rating during installation and operation?
The IP68 rating depends entirely on proper installation of the stainless steel locking ring and silicone gasket. Apply a thin bead of marine-grade silicone sealant around the panel cutout before inserting the switch. Tighten the locking ring to 8-10 Newton-meters using a 19mm wrench, ensuring even pressure. Do not over-tighten as this can crack the anodized bezel. After installation, allow the silicone sealant to cure for 24 hours before exposing the switch to water. Inspect the seal quarterly in harsh environments and reapply sealant if visible cracks appear.
