Hi cfoek,
Check for "555-circuits" or 555 timer/555 monostabil multivibrators & even general: triggered timer circuits...., we have such at EdaBoard too...
K.
Simplest solution is for you: per switch loaded serial RC element of 1uF & ca2.7MOhm to basis of a transistor, their Collector/Emitter has your relay...
