Backlit Potentiometer+Switch Offers Dual Control Options - SW44635

4/21/2009

Electro-Mech's new SW44635 enhanced backlit potentiometer switch offers both rotary and push-on/push-off functionality plus LED backlighting for maximum operational control. The compact all-in-one unit saves valuable panel space in applications where there are tight design limitations.

The DPDT 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 a backlit knob and an alternate action pushbutton switch, the SW44635 utilizes two discrete LED's that backlight the translucent knob in all standard LED colors. Typical applications for the SW44635 switch include industrial/avionics displays and audio controls, instrument panel controls, and other high-density panels. Previous models were only available for edge-lit panel installations.

Lightweight, the compact unit weighs less than one ounce and measures less than one inch in diameter. The SW44635 requires approximately three inches of space behind the display panel and mounts via two mounting screws into the front panel. Interconnection is provided via either wire leads or solder terminals.

The SW44635 is rated at 30 VDC or 120 VAC, 2.0a resistive, 0.5a inductive. Potentiometer resistance is 10K ohms (+/- 10%) but can be customer specified. Other features provided by the SW44635 include push-on/remain-in/push-off switching, an operating pressure of 32 oz. (+/- 16 oz.), plunger travel of approximately 0.24¨, and a rated switch life of 50,000 minimum actuations.
