Which is the best Go Switch for mechanical limit switches?
GO Switch models 11, 21, 31 and 81 are the ideal replacements for traditional mechanical limit switches. Sealed contacts, rugged housings, non-contact detection of ferrous metal & magnetic targets, and snap action response make these switches the ultimate problem solvers for troublesome mechanical limit switch applications.

What happens when you close a 120 V switch?
When you close the switch there would be close to zero volts ACROSS the switch. There are problems with this measurement. The 120 V that you measure might not be able to carry an appreciable current. The switch when attached to a load has a very small voltage drop. The contact resistance could be 0.010 ohms.
What are the dual Hi-Lo pressure switches used for?
Application Information The Dual Hi-Lo pressure switches in this catalog consolidate control, alarm and safety shutdown applications into one instrument. For hazardous locations, a hermetically sealed explosion-proof, stainless steel, switching element capsule (DPDT or SPDT) is provided for each sensing assembly.

What should the voltage be on a switch?
Measure between one of the black wires on the switch and the white wires. If it’s the black wire going to the wire nut you should read 120 VAC. If it’s the black wire going up the sleeve on its own then with the switch in the ON position you should have 120 VAC.
How does a low voltage going to switch work?
It doesn’t, it just keeps your meter from giving false readings. AC power comes in on two wires, the hot and the neutral. Hot has the voltage while neutral is connected to ground somewhere so there is little voltage on it. It is actually safe to come in contact with this (just don’t try this at home!).
