Medium Duty Battery Selector Switch w/Key Lock Perko's 8501 Series battery selector switches are among the most popular battery switches ever produced. 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. Specifications: Diameter: 5-1/4" Depth: 2-5/8" For use with 6 to 50 Volt Marine Electrical Systems Capacity - 250 AMPS Continuous, 360 AMPS Intermittent When used with Non-Unitized Alternators, these models will interrupt the field current (reducing the possibility of damage) if turned "OFF" with the engine running

Mini Battery Selector Switch The 701S is the most compact selector switch available on the market. While BEP recommends isolated battery systems as outlined with our distribution clusters, the 701S provides a simple economical way of separating two batteries. BEP Marine Battery Switch Test Procedures (UL 1107) Continuous (1 hour), intermittent (5 minutes) and Cranking (engine starting - 10 seconds). The test is to determine the maximum current the switch can handle for the stated time, without the rear terminals exceeding 100 deg C (212 deg F) above the ambient temperature. The continuous and intermittent ratings are tested at 110% of specified ratings. All BEP switches are tested Independently to this specification by a 3rd party laboratory. Housed in the same dimensions as the 701, and includes the same removable side plates and back cover Please note selector switches will not separate electronics from harmful engine starting spikes Tin-plated copper studs and nuts Ignition-protected WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm.
