Don’t Settle for Poorly Improvised Switch Covers

No one wants to explain to the plant manager why the control switch in their substation, power plant, or factory was operated by accident.  Neither does anyone working in an industrial electrical facility love worrying about how someone might bump into a control switch or catch their toolbelt on a control switch handle.

In the past, solutions to this problem have been half-baked and have come with big downsides.  Drawing lines on the plant floor can be bypassed, uninstalling pistol grip handles means they might be hard to find in the event of a real emergency, and cardboard taped over a rotary control switch is just downright unprofessional.

Furthermore, other commercial solutions tend to lock you into a feature that you may not really want.  Our rotary switch covers were designed by a systems technical specialist to be feature-agnostic yet simple and functional at the same time.
