Their use of the traditional Perko bolt circle makes for easy installation, whether new or as a replacement. These switches can be mounted in numerous locations. And as ignition protected switches, they can be installed in the engine rooms of gasoline powered boats. In addition to doing everything a battery disconnect switch does, battery selector switches permit battery selection (of two or more batteries) for specific purposes including starting engines, running accessories or even recharging. They allow for the use of one or more batteries in systems with one or more engines and facilitate putting batteries in parallel for emergency starting when one or both batteries are substantially discharged. Perko battery switches are designed for surface mounting. Standard duty switches have a bright red polycarbonate housing for safety with a large easy-to-turn black knob. The housing of the heavy duty switches are red fiber-reinforced polycarbonate. Selector switches are designed with a make before break feature. This allows switching between the 1, the ALL and the 2 positions while the engine is running. Models with an Alternator Field Disconnect feature offer protection for Non-Unitized Alternators should the switch accidentally be turned to the OFF position with the engine running. Versions of the 8501 Series switches offer additional features such as alternator disconnect and key lock security. The 90° rotation feature allows users to feel the switches' position in no light situations and the classic shape of the knob makes it easy to turn. High conductivity studs are long enough to handle more than 1 cable and strong enough for torque needed for secure connections. Optional spacer ring (PN 0462DP0RED) allows for the use of larger cables.

Install was easy and works just fine. My last one was 20 years old. Hope this one lasts.

I had a stereo installed in my 1988 Mastercraft, and as I was telling the salesman what i was looking for, he enlightened me to the Perko Battery Selector Switch. Then he showed me one, and I said I would purchase one and bring it to them on the day of the install. (He was saving me money, by not purchasing the product from him.) It is of solid material and very easy to use. If I was going to install this product myself, it would've been fairly simple, but since they were going to be installing the stereo equipment for me, I let them do the professional work. Very satisfied with the ease and convenience of this product. It is so much more comforting to be shutting of all of the batteries, using 1 battery, using the other battery and/or using both batteries. I highly recommend.

Make sure to read the size of this thing. It's very large but sturdy. It absolutely does the job. Keeps us feeling safe on the water with battery power. We can switch batteries or leave both on. It's really nice when you like to pump music while out on a bank. You don't have to worry about going out to a dead battery!
