...electronics design should be such that enclosure is expected. If significant heat is expected to be generated and require dissipation, this should be noted, but hopefully this will not be a concern as low electrical consumption is a design requirement. 8. Anticipated height with enclosure should be less than 1cm, ideally; up to 1.5cm is OK. 9. The "on" signal should be sufficient to control a MOSFET relay, preferably 5V. One idea for the pressure sensor is to use a material such as Velostat or Linqstat that reduces resistance under pressure. However, I need you to design the circuit for it.
