Electro-Mech has introduced a potentiometer switch that offers both rotary and push-on momentary functionality for maximum operation control. The compact SW44585 all-in-one unit saves panel space in applications with tight space constraints.

The SPST switch enables the user to specify a value so that at the push of a button the circuit or channel automatically opens at the preset level. Featuring an optional edge-lit knob assembly and a snap-feel momentary switch actuation, the SW44585 takes up less than 1-inch behind the panel. Typical applications include industrial/avionics displays and audio controls, instrument panel controls, and other high-density panels. Previous models required additional behind panel depth.

The lightweight unit weighs less than one ounce and mounts a Vishay/Sfernice potentiometer module with a custom PCB tactile switch. The SW44585 mounts via two mounting screws into the front panel and interconnection is provided via wire leads or solder terminals.

The SW44585 is rated for 5-100mA load at 0.1-5Vdc. Potentiometer resistance is 10kΩ+10 per cent but can be customer specified. Other features include snap-feel momentary switching, an operating pressure of 14 oz. (+3 oz), plunger travel of approximately 0.02-inch nominal, and a rated switch life of 500,000 minimum actuations.

Pricing starts at Rs.813.59-Rs.1,241.80 ($19-$29) in quantities of 1,000, depending on options. Delivery is 10 weeks ARO.
