Potentiometer switch offers both rotary and push-on functionality with light pipe
The compact all-in-one unit saves valuable panel space in applications where there are tight design limitations. The SPST-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. The SW44884 assembly features a backlit shaft with knurled button, an alternate-action pushbutton switch, a clear light pipe switch shaft, and a 10kOhm resistance potentiometer module. Typical applications include industrial/avionics displays and audio controls, instrument panel control, aircraft simulator controls, and other high-density panels. Previous models were only available using edgelit knobs and did not include LED backlighting. The user may also jumper the LED circuit to one of the switch circuits for LED switching. The SW44884 also features side facing PC pins for easier interface to the PC Board in the next higher assembly. Lightweight, the compact unit weighs less than one ounce and measures less than ¾” square. The SW44884 requires approx. 50mm of space behind the display panel and mounts directly to the PCB via side and rear facing PC pins. The SW44884 is rated at 0.10A resistive at 30 VDC. Potentiometer resistance is 10kOhm +10% but can be customer specified. Rated switch life is 100,000 minimum actuations.
