Door mounted pump down switch

[cboylan]

I'm looking for a simple lever actuated control SPST to use on a W/I freezer door to open the circuit to the evap fans and LL sol. when the door is opened.

I've searched grainger's but haven't found what I'm looking for. Has anyone purchased and used such recently?

Please give any details.

Hi, cboylan,

You can get from Grainger # 2EH73 limit switch.
We use on air blast freezer doors.

I've always used an Allen Bradley limit switch with an actuator arm that has a roller on the end of it. It's an oiltight unit, dpst. Pretty standard unit. Just ask your industrial electrical supplier for limit switches and they should be able to hook you up. You mount a tab at the top of the door to actuate the switch arm.
