Compact Potentiometer Switch
Supplier: Electro-Mech Components, Inc. Part Number SW44585
Electro-Mech’s new SW44585 compact
potentiometer switch offers both rotary and push-on momentary functionality for
maximum operation control. The compact all-in-one unit saves valuable panel space in
applications where there are tight design limitations.
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 edgelit
knob assembly and a snap-feel momentary switch actuation, the SW44585 takes up less
than 1.00” behind the panel. Typical applications for the SW44585 switch include
industrial/avionics displays and audio controls, instrument panel controls, and other
high-density panels. Previous models required additional behind panel depth.
Lightweight, the compact 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
either wire leads or solder terminals.
The SW44585 is rated for 5-100mA load at 0.1-50.0 VDC. Potentiometer
resistance is 10K-O+10% but can be customer specified. Other features provided by the
SW44585 include snap-feel momentary switching, an operating pressure of 14 oz.
(+3 oz.), plunger travel of approximately 0.020” nominal, and a rated switch life of
500,000 minimum actuations.
