Product details
The Pentair 155187 is a double insulated toggle switch, listed for the MiniMax Plus HP. It is the genuine Pentair replacement part.
Why a specific switch
The double insulation is not incidental. A switch in this position carries line voltage in a wet outdoor cabinet, and the second insulation layer is the reason it is safe to reach for. A generic toggle of the same current rating is not a like for like substitute.
The symptom it fixes
A unit that will not come on, when there is power at the panel and everything downstream tests good, often comes down to the toggle. Contacts wear, the mechanism loses its snap, and the switch stops making a reliable connection. It is a small part standing in front of an expensive machine.
Before you start
Isolate the power at the breaker and confirm the panel is dead before you open it. If working inside a live rated cabinet is not something you do, this is a job for a service technician.
