VCMS Switch Panel System
Model VCMS-SP12
1. Product Description
The Switch Panel System consists of a six-position switch module, a six output power module and a 15 ft. communications
logic cable. It is used in applications that require the driver to operate auxiliary vehicle 12 volt devices such as interior and
exterior lights, heaters, warning lights, beacons, pumps, etc.
The system contains a VCMS-SM6 Switch Module with six push buttons that are back lighted to allow easy night viewing.
Each push button accomodates a custom legend and contains a status LED that indicates if the switch is on or off. The
anodized aluminum case features a low profile measuring only 0.55 inches high, allowing mounting location flexibility. It is
mounted to a flat panel via four 0.70 inch long 6-32 threaded studs. The case design is an aluminum two-piece clam shell
held together by two screws on each side. The module can be easily opened to install the switch legends. The module
contains a 10-position connector on the rear for the communications logic cable connection. A mounting cutout template
is shown in Figure 3.
The system’s VCMS-PM1 power module is remotely located from the switch module and connected with the communications
logic cable. The power module contains six 12 volt 15 amp outputs for powering the auxiliary loads. The power
module has a maximum current rating of 60 amps (total of all six outputs). The outputs provide automatic shutdown
protection for short circuit and overload conditions. Three +12 volt (BAT) terminals are provided for the incoming power.
Each terminal must be connected to the battery with an individually fused (20 amp) wire. Note that all six internal power
switches are powered from a common 12 volt bus that is connected to the three +12 volt BAT terminals. A mechanical
drawing of the VCMS-PM1 Power Module can be seen in Figure 4.
The power module’s four digital inputs allow external signals to be monitored by the system. These signals are voltage
levels between zero volts (chassis ground) and battery voltage. Typically these inputs are from a contact closure such as
a switch to either ground or +12 volts. The VCMS application program defines each input as actuated by either a ground
or +12 volt input. The program for this systems uses input I-1 to monitor the Ignition Switch status so it is activated by a
+12 volt signal. Wiring terminations for the power outputs, digital inputs and the +12 volt supply utilize 0.25 inch faston
blade terminals. The communications interface utilizes a 10-pin connector.
Input I-1 (Ignition On) activates the switch back lights and enables switch operation. Each switch is programmed to operate
as either a 2-position latching (push to turn on, push again to turn off) or as a momentary switch (on for the durration
the switch is depressed). This system is programmed to have switches SW3 through SW5 operate as 2-position latching,
and SW1 and SW2 as momentary.
