Very common in bambulances and fire trucks - they use a relay that looks like a starter solenoid but unlike the solenoid is designed for continuous duty cycle - most auto supply and emergency equipment suppliers have same.
Be careful - once got one used with a golf cart - 24 to 36 volt coil would not call in reliably at 12 VDC. Ssb Yahoo!
