Relay switch to light
WebSo when light shines on the photocell, it turns the transistor on, which energizes the relay's electromagnet, which turns the light off. When it is dark, the photocell has high resistance, so no current flows through the base and the relay is not activated -- the light is on. In a real street light the circuit might be a bit more advanced, but ...

WebAn impulse relay is a switching device designed to control electricity consumers. It works as follows: every time the switch is pressed, the built-in terminal of the relay changes its state – e.g., from switched on to switched off, etc. With impulse relays you can organize lighting control from various locations. WebFeb 22, 2024 · Hi - it uses 24V DC to operate the relay (good) and you want to use a switch inside it to operate a 230V AC light (also good as it says rated to 250V and 5A). Using the 24V door controller output the relay may only be energised when the motor needs to be on (i.e. for 20 seconds while door is moving ...). Remember safety safety safety.
