How do you check a photo control switch for continuity?

To check a photo control switch for continuity, you will need a multimeter set to the continuity test function. Disconnect the switch from the circuit, then touch one probe to each terminal of the switch. If the multimeter beeps or shows continuity, it means the switch is functioning properly.


What alteration would occur if a single pole switch is reconnected to become a master switch?

If a single pole switch is wired to be a master switch, the switch would have to be in the on position for any other control devices to operate. Turning the master switch off would eliminate power to all devices (and/or loads) which it was serving. For example, some homes have a switch to control their outside light. If the outside light has a photo eye (the light will only come on at night), the switch is the master switch. Another example would be the breakers in an electrical panel. Each breaker would be the "master switch" for the circuit it protects. The main breaker in the panel would be the "master switch" for the entire home.

What is a light sensitive switch?

A light sensitive switch, also known as a photoresistor or photocell, is an electronic component that changes its resistance depending on the amount of light it is exposed to. When the light level changes, the resistance of the photoresistor changes, causing it to switch the circuit on or off. This is commonly used in applications such as street lighting, security systems, and camera exposure control.


Can you operate a hunter fan with a dimmer switch?

What is the difference between a proximity switch and a photo switch?

A proximity switch operated when you bring your hand or finger close to it. That's what's in lamps that turn on when you touch the base of the lamp. A photo switch operates when light shines on it. That's what's on streetlights that turns them on automatically after dark.
