Just thought I'd put this out there. Mouser sell a small 4PDT Omron relay for a very reasonable price. This is a small signal relay and is very quiet in operation.
The 4PDT is useful if you have a HRM setup and want to switch the PAB on simultaneously with the overdrive channel.
They also sell the DPDT version and they are available in multiple coil voltages including 5, 6 & 12V.
4PDT 6V - 653-G6A-474P20-DC6
