on the ss2 safety switch does it have a normally open contact or is it normally closed?

The switch is normally closed. The float lifts and opens (disconnects) the thermostat circuit if the water backs up in the drain pan or drain pipe.

I believe the switch is open when the plunger is out. Then the alarm is armed the current runs through the wires and the switch. When the current is Brocken it trips the alarm. This keeps a robber from cutting a wire. It will also trip the alarm if this happens. Hope it helps.

If it is making constant contact, thus allowing constant voltage on your opener from a full time closed loop instead of a momentary pulse, which it should be doing, then yes it will keep the opener in one position. It is an override for the safety sensors at the bottom of the door. If the sensors fail, the only way to close the door is to stand there and hold the button down until the door is fully closed. If this is not the first time you have had to change the button, then I would guess that you have a short in the wire, most commonly caused by a staple shorting the two wires together somewhere between the button and the opener.

Two. it is a low voltage open / closed switch. I use mine to open / close my garage door when I can't find the remote.

The exact model is on a sticker well inside the unit and believe it or not the number is not listed in the Owners manual. I didn't have time to open it up before leaving for work this morning but I'll look tonight and if someone else hasn't already given you the answer, I'll answer it then. Well, I took the outside cover and the inside protection cover off and did not see either of the numbers that you gave. However, there is a rather large Disconnect Switch right there in front of the box on the right hand side. So the switch that came with mine definitely has the service disconnect installed in it. Let me know if you want me to email you a picture.

No, it doesn't have to be in contact with any surface. It is simply a switch that connects in series or connects a circuit.

Haven't tried it but the safety lock is only a one "click" not 2 like others that I have.

Normally open. Applying current to the switched side will close the load side.

The chassis of the switch connects to a sheet metal ground. There is a spade lug on the center pin that you connect the ground lead to whatever device is being connected. The circuit is completed when the switch is relaxed (fully up) and breaks when closes.

I never notice the switch or use it, I just been shutting the switch off myself, unlrsd you put it on s timer

When the beam is broken between the two devices it merely closes or opens contacts to the connected device (a sliding gate in my case, it causes the closing gate to stop and then open). It is activated as long as the beam is broken.

No - it is operating as expected. The N/O and N/C contacts are just a switch from an electromechanical relay. You need to either ground or apply voltage to the common terminal - depends on how you use it in the circuit.

You have to continue to hold the switch down or it shuts off. I see it as a safety.

Its mostly cosmetic and you don't have to use it. If you use it you can set it up so you would lift the cover then activate the switch preventing any unintentional activation. By closing the cover you also deactivate the switch.

It is a full ON-OFF switch. Flip the safety cover up and you can turn ON something. Flip the safety cover down and it turns OFF whatever.

this utilizes only 1 set of contacts for the LOAD. (the 2 large screw treminals). think of it as a simple on/off switch (single pole single throw)(SPST). hope this helps
