It is an electric heater, with the heating elements in a straight line (a strip)
There are usually 2 on a domestic electric heater, one about a foot from the top and the other near the bottom, both attached to the elements.
Perspex can be softened and shaped using a strip heater. The strip heater heats the Perspex material to a malleable state, allowing it to be bent or formed into the desired shape.
A strip heater is typically used to heat surfaces for applications like plastic bending or sealing. To use a strip heater, you would place the object to be heated on top of the strip heater and turn it on. The heat generated by the strip heater will soften the material, allowing it to be formed or sealed as needed.
If you are talking about a wall switch for the heater, check to see if the heater has its own internal thermostat or switch as this might be in the off position and not allow the heater to turn on. If you are talking about a switch on the heater itself, then yes in all probability the switch is not working.
A limit switch is a switch that will shut off a burner at the highest temp that is allowed. Example:If the limit is set at 200 degrees, the inside of your heater will heat up to that temp, then the burner will shut off. The blower motor or circulator pump will move the air or water around your house. When the inside of your heater cools down anywhere from 15-25 degrees, the burner will come back on & the cycle repeats itself over & over until the thermostat is satisfied.
I had the same problem. Turns out it was the thermal limit switch. Very inexpensive and easy fix.
