ESWA ceiling heating switch broken

Newbie_John

As this is very uncommon these days I struggle to find any information, we have ceiling heating with switches as shown in picture - the problem is one of the switches broke and heats anytime when the temperature drops below 22*C, does anyone know where I could get a replacement ? Or which other switch would work?

It says "30   GBP" and "Send message"

Also it says "Standard ceiling heating thermostat. Simple Bi-metallic heating control for ceiling heating systems", that means that it can be replaced with pretty much any thermostat with adequate switching power
