A3PJ

This is the description about A3PJ of the lighted pushbutton switch, rectangular type with 18.9 mm * 26.1 mm button.

Here are the features of A3PJ. Back-projected LED offers longer life, wider viewing, and greater viewing distance; Replaceable LED T-1-3/4 standardized for ease of maintenance; Two choices of contacts to match load requirements: silver and gold; Snap-action offers high reliability; Lamped type also available; Button lockable; LED protected by a current-limiting resistor.

The characteristics of A3PJ are these. Operating frequency: mechanical is 120 operations/minute max and electrical is 30 operations/minute max. Operating force: momentary action is 600 g max and alternate action is 700 g max. min. (at 500 VDC). Dielectric strength is 1,000Insulation resistance is 100 M VAC, 50/60 Hz for 1 minute between terminals of same polarity and is 2,000 VAC, 50/60 Hz for 1 minute between terminals of different polarity, between current-carrying metal part and ground, and between each terminal and non-current-carrying metal part. Vibration Malfunction durability is 10 to 55 Hz, 1.5 mm double amplitude. Shock: mechanical durability is 200m/s2 (20 G). Ambient temperature: operating is from -10 to 40. Humidity is 35 to 85% RHmax. Life expectancy: mechanical: Momentary-action type: 1,000,000 operations min; alternate-action type: 200,000 operations min; electrical action type: 100,000 operations min (see note below.). Weight approx is from 20 g to 24.5 g.

These are the notesabout A3PJ: With the alternate action type, one operation cycle consists of set and reset actions.
