ENER-J Wireless Kinetic Switch Silver

ENER-J wireless kinetic switch (silver) options — these are battery-free wireless wall switches that generate their own energy when pressed and work with an RF receiver unit (receiver usually sold separately):

Important things to know
Battey free operation – the switch generates power when you press it, so there’s no battery or mains supply at the switch itself. Receiver required – the switch sends a signal (usually 433 MHz) to an RF receiver module that actually switches the light or load. This receiver is not always included, so check before buying. Dimmable support – many of these models support dimming via long press and keep brightness memory, but you must pair them with a compatible dimmable receiver. IP rating – many silver models are IP65/IP67 rated for splash/dust protection, meaning you can mount them indoors or in sheltered outdoor spots.
