Low water indicator, mechanical, model WMS-WP 6, DN20 (¾")

Float-based, with electric switch, test and unlock switch.
If the water level in the hot-water boiler drops below a minimum value, a switch is actuated which interrupts the current supply to the boiler furnace. A lock prevents it switching on again independently.
The float can be pushed downwards and the water shortage simulated.
