Omni Pro Electronics has announced its release of the new TH Series of Switches from CIT Relay & Switch. The TH Capacitive Touch Anti-Vandal switch is offered in 16mm, 19mm, 22mm or 25mm and is available with 30-Second Hold, Momentary Switch or a Latching Switch mounting options.

A touch-controlled capacitive switch operates by measuring change in capacitance when depressed. When touched, the electrical charge disrupts the switch's own electrical charge, causing a change in capacitance. The CIT Relay & Switch capacitive touch TH Series is ideally suited for use in vending machines, gated community guard houses, traffic controls, industrial controls, appliances, infotainment centers and more.

CIT’s TH Series Capacitive Touch Switch is available with a flush illuminated actuator with two ring size options, each with a brushed stainless steel finish.

Most come with a standard bezel, the 16mm comes in a 4.5mm-high bezel. LED color and state options include single or dual LED with LED voltage choices of 5VDC, 12VDC or 24VDC and max current of 15mA. Single LED colors include red, orange, green, blue and white available in "Off / Color" and "Color / Off" states. The Dual LED colors are designed in red-green, red-blue, blue-green, white-orange and in the reverse orders. Its dielectric strength is 250Vrms min between contacts with an insulation resistance of more than 10MΩ min @ 600VDC and an operating temperature of -40°C to 85°C.
