Airbag Switches for Law Enforcement

Gold Contacts |
Gold Contacts in the airbag switch are important because gold doesn't corrode, and the switches will last far longer than non-gold contacts. Other metals are used in switches when the current is high enough to insure that the contacts clean themselves when the switch is moved from one position to another. But in an airbag circuit, the current is well below 3 milliAmps, so corrosion of the internal switch contacts is inevitable. This is well known to engineers in the electronics industry, and is why they use gold in low current applications. In the Auto industry, gold contacts have been required on low current electronic circuits since WW2. An airbag switch that doesn't use gold contacts can eventually fail because the buildup of corrosion on the internal contacts will add too much resistance into the airbag circuit.
A switch with gold contacts needs to be soldered with techniques that carefully control the solder temperature and exposure time otherwise, the switch contacts tend to pit (the gold melts off the substrate). This can have a significant effect on the Airbag Switch's longevity.
Hand soldering lacks precise control of soldering temperature and time of exposure to soldering heat.
All Airbag Switches by Sensible Solutions are made using computer controlled wave soldering of the circuit boards. This carefully controls solder temperature and exposure time for quality assurance and long life.

RF Filter built into switch circuit |
Each airbag switch has internal filtering (patent pending) that removes Radio Frequencies (RF) from the circuit and protects the airbag from accidental detonation because of inductive reactance.
There are numerous frequencies in the radio frequency spectrum reserved for police, government and emergency use. These frequencies include the ones police cruisers, fire and emergency vehicles use for communication. The problem is that without a filter, any wire can pick up radio waves just like an antenna. Depending on the frequency and the length of the wire itself these radio waves can create a current in the airbag switch wire. An airbag circuit, requires very little current to detonate an airbag. These RF waves can produce a detonating current unless they are filtered out.
Sensible Solutions is the only airbag switch manufacturer that uses an internal filter circuit to remove any RF induced currents, so these switches will not induce accidental detonation from radio frequencies.
Sensible Solutions makes the leading technologically superior airbag switch to insure long life and reliability. All of our airbag switches carry a full five-year full replacement warranty.
We offer our switches as kits, complete with photo- illustrated instructions and technical support by phone. Or, if you prefer, our certified installers can install the switches for you or coordinate with your Mobile Data Terminal (laptop) installation contractor.
Incorporating a state of the art design, Sensible Solutions airbag switches (Patents Pending) can be used in all vehicles, with no adverse effect to the SRS computer or diagnostic monitor. As Federal regulations require, our airbag switch allows an airbag to be turned ON or OFF while maintaining proper functioning of a vehicle's diagnostic system in either position. The vehicle's air bag warning light on the instrument panel will continue to provide accurate indications of the status of the other airbags in the SRS system.
Sensible Solutions airbag switches lead the industry in quality and reliability. Our design is sealed in a moisture/dirt resistant enclosure with all switch contacts double sealed against corrosion. We use one light to show when the airbag is turned off, as required by Federal regulations. Other switches have two lights, making it difficult for many people to tell if the airbag is on or off. We have found that one light showing when the airbag is turned off is far easier for most users.
Our switches can be used to control curtain airbags as well. But with curtain airbags, which can destroy prisoner partitions, you can use one of our airbag simulators to disconnect the airbag without effecting the car's airbag system.
Covert Operations
For covert surveillance vehicles, we have provided airbag switches with red LEDs to preserve night vision. A big issue to those who use these vehicles is making sure the airbags do not go off unexpectedly; especially when they are trying to exit the vehicle quickly. This is one reason they have decided on manually controlled airbag switches.
