Please note:

• Switch closure — MAINTAINED vs. MOMENTARY:
  Single switch applications use a MAINTAINED closure switch. Multiple switch applications use MOMENTARY closure switches.
• Switch for sequencer:
  You may want a switch that has two LEDs to indicate when power is cycling up (on) or down (off). If your sequencer has the ASM (Alternate Sequence Mode) feature, use switch model RPSB-KP-ASM
