Illuminated Push Buttons

Typically, you use one of the spare contacts to operate the lamp. Industrial controls are usually 24 VDC. Having even current limited 120 VAC is a shock hazard when changing lamps.

I know, I got annoyed when a manufacturer changed the design of their lamps and captured the heat with an O-ring and the plastic on the lens just cracked. So, eventually 100 of these push/button and lamp combo were replaced by IDEC LED combos. Yea, you had to pick the same color LED and lens face. Well worth not having to relamp.

I used these AL6 series lamps. https://www.newark.com/catalog_129/index.html?page=1757 I used the rectangular ones because they were easier to label. You label under the lens. Printing on transparency film works.

Watch it, you have to buy parts separately.

Check the specs and find out what the lamp base is. You may be able to change to a lower voltage. Personally, don;t use incadesent bulbs. They get dimmer, but don;t burn out.

Here's the data sheet on it

these buttons have incandescent or led lamps rated for 120 vac, so no messing around with cap, diodes or resistors.

Looks like that they do have the latching push on/off that I was looking for

Thank you
