Push button switch (pulsador eléctrico)
A wiring accessory that only closes the circuit while you hold it down and springs back when you let go. It is used for doorbells, stairwell light timers and to send orders to latching relays and smart home systems.
What a pulsador is
A pulsador is a push button switch (momentary switch in the US) that gives a brief signal: a spring closes the circuit while you press it and opens it as soon as you let go. It has no on or off position; what happens next is decided by the device that receives the signal.
Push button or switch
A switch stays where you leave it and feeds the light directly. A push button does not feed the light: it sends a pulse to another device, such as a doorbell, a latching relay (telerruptor), a timer or a smart home actuator. If you replace a push button with an ordinary switch by mistake, the installation stops working properly.
Where it is used
- Doorbells: the bell rings while you hold the button.
- Stairwells and entrance halls: each floor has a button, often illuminated, that starts the stairwell light timer.
- Latching relays: each press toggles the light, from as many points as you like.
- Motorised blinds: up and down buttons.
- Smart homes: buttons that trigger scenes.
Illuminated push buttons
A small pilot light makes them visible in the dark, and they are standard in communal areas. If the stairwell light never goes off, the cause is sometimes a stuck button or a badly wired pilot light that keeps the order active.
Replacing one
It is simple as long as you fit another push button, not a switch. A simple accessory costs 30 to 50 euros plus VAT fitted, as a guide. In communal buildings, see building maintenance in Seville, Spain.
