SW44687 potentiometer switch assembly

From Electro-Mech comes the SW44687 potentiometer switch assembly that offers both rotary and push-on functionality for maximum operation control.

The compact all-in-one unit saves valuable panel space in applications where there are tight design limitations. The SPDT 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 edge-lit button (optional) and a momentary snap-click pushbutton switch, the SW44687 also features a 10k&@8486; resistance potentiometer module. Typical applications for the SW44687 switch include industrial/avionics displays and audio controls, instrument panel controls, and other high-density panels.

Previous models were only available using EMC's slide bar switch actuation design. The unit requires less than 25mm of space behind the display panel. Interconnection is provided via either wire leads, PC pins or solder lug terminals.

The SW44687 is rated at 30Vdc or 120Vac, 1A resistive, 0.25A inductive. Potentiometer resistance is 10k? +10 percent but can be customer specified. Rated switch life is of 100,000 minimum actuations.
